Allolee To Walltown
__NOTOC__ Allolee to Walltown is the name given to a Site of Special Scientific Interest (SSSI) in Northumberland, England. The site, which follows the path of a section of Hadrian's Wall, is notable for an unusually wide range of grassland types growing on thin soil above the Whin Sill, a rock formation peculiar to the Northern Pennines. Location and natural features Allolee to Walltown is situated in the north-east of England, some east-north-east of Greenhead and north-north-west of Haltwhistle. It is an east-west corridor of land straddling Hadrian's Wall for a distance of between Milecastle 45 (Walltown) to the west, and Turret 43B in the east, just short of the fort of Aesica (Great Chesters). Milecastle 44 (Allolee) is found at approximately the middle point of the east-west SSSI site. The site is situated on the Whin Sill, igneous rock dolerite found in County Durham and Northumberland, which outcrops as high, rocky cliff lines, and which was used by the builder ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Agrostis Capillaris
''Agrostis capillaris'', the common bent, colonial bent, or browntop, is a rhizomatous and stoloniferous perennial in the grass family (Poaceae). It is native to Eurasia and has been widely introduced in many parts of the world. Colonial bent grows in moist grasslands and open meadows, and can also be found in agricultural areas, roadsides, and invading disturbed areas. The name '' Agrostis'' comes from the Greek word meaning forage plant, ''agros'' meaning "a field". It is found growing in neutral to acidic soils. It has a very fine texture and like most bent grasses grows very dense. Although this species is used on golf courses, providing some of the best ball playing surfaces in the world, it also produces a spectacular visual appearance when maintained properly. It provides an excellent home lawn but is not tolerant of heavy use. Colonial bent is fairly easy to grow from seeds and fertilization of the lawn is not as intense. This grass also takes longer to establish t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festuca Rubra
''Festuca rubra'' is a species of grass known by the common name red fescue or creeping red fescue. It is widespread across much of the Northern Hemisphere and can tolerate many habitats and climates. It is best adapted to well-drained soils in cool, temperate climates; it prefers shadier areas and is often planted for its shade tolerance. Wild animals browse it, but it has not been important for domestic forage due to low productivity and palatability. It is also an ornamental plant for gardens. Description ''Festuca rubra'' is perennial and has sub-species that have rhizomes and/or form bunchgrass tufts. It mainly exists in neutral and acidic soils. It can grow between 2 and 20 cm tall. Like all fescues, the leaves are narrow and needle like, making it less palatable to livestock. The swards that it forms are not as tufted as sheep's fescue (''Festuca ovina'') or wavy hair grass (''Deschampsia flexuosa''). The tufted nature is what gives the grass its springy characterist ...
